It could also be due to, or exacerbated by, a dried out electrolytic
filter capacitor in the DC supply circuitry.

It occurred to me that if I posted the pictures of these relays, that it
would be easy for somebody that is more familiar with this type of
equipment
would be able to tell me if these relays have AC or DC type coils:

Thanks for your reply.

These relays are all designed to be energized by an AC source. The copper
shunt at the end of the pole piece is characteristic of AC relays. Is there
a 24 volt transformer anywhere in there and do all of the relays chatter, or
just one?
